ALBERT P. LEE, or cnreneo, ILLINOIS.

Be it known that'li, ALBE T P. LEE, a. citizen of the United States, residingat Chicago in the county of Cook and State of Ilhnois,.have invented a certain new and useful Improvement in Movable Loading- Hoppers, of whichthe following is a full,

clear, concise, :and exact description, reference. being had to the accompanying drawings, forming a part of this specification. v

My invention relates .to loading devices and has'for its object'the provision of a device of this character which may be readily and easily manipulated to take a load of material, to be. thereupon moved into adischarge position, this movement taking place upona suitable carrier or frame upon which this; what might be called movable hopper, may operate.

My invention will find various, applications; and I will describe herein one form which it may take together with a' modification.

.irrIn 'wthe particular form -herein shown, I

have what might be called a movable loadinghopperwhich may roll upona suitable framework, which framework is so arranged that it may for instance be placed upon the side of a gondola car, that is, a car of the ordinary fiat car type having the necessary two sides andtwo ends. The device in this form is so arranged'that this movable loading hopper may roll first into its charge receiving position and may thereafter be tilted to its alternate'or load discharging position.

I will describe my invention more in detail by reference'to the accompanying drawing illustrating the same in which Figure l is a side view of my improved loading device; Fig. 2 is an end view thereof; Fig. 3 'sets forth an end view of a modification; Fig. 4 sets forth a side view of the. modification in'Fig. 8, and Fig. 5 sets forth the collapsible character of the framework.

Referring specifically' to Figs. l and 2, I show a side wall 1 of a gondola carand the floor 2 thereof. The loading device consists of a framework which may be said to provide two rails 3; 3 preferably constructed of T iron. porting members 4, 4 are secured to the rails 3 and are further held in place by the diagonal members 5, 5 respectively. The framework thus far described comprises the rail Two downwardly extending sup MOVABLE nonnnvc norrnn.

4 Specification of Letters Patent. Patented 19; 1915. Application filed October 29, 1912. Serial No. 728,398. A I 3 order to permit the saidhoppertolrollfrom one alternative position shown] in dotted.-v

lines in Fig.1 toits-other alternative posi-Y tion shown in dotted lines in Fig.1. The lower outside face of-this circular portion of the hopper 6 is provided with'two guide sections 8; 8 respectively having flanges 9, 9 i so arrangedthat when this hopper ismounted upon the rails 3, 3 the flanges 9, 9 hold the frameportions inplace andat the same t me retain the. hopper upon-these rail portions so as to permit thisihopper to roll gfreely'from one alternative position to the other. In order. furtherto guide the movement of th' hopper over the rails 3; suitable ".pins. 10 a e provi de'd: adapted to engage openings or apertures 11 provided-in these "rails; Two chains -12 and 13 respectively are fastened to theoppositeends of the rail 3 and serve tolimit the movement as shown in dotte'd lines in, :Fig 1 to which said hop per may be. subject. l I v I In the operation of the dev'icethe hopper 6 is moved into the right hand position of Fig. I where it is loaded by operators within the car, whereupon lthishopper isthen moved into the left hand dotted position. of, Fig- 1 wherebyit is permitted to discharge its contents 0 1j.the chute l into possibly a waiting vehicle orotherwise as may be des red.

Normally when the hopper is iipon the sides of the car it should occupy the right halrdposition of F l s o that the left hand extremities of the-elements, 3,an d 5 may be swung about. their pivots 15, 161'respectively .againstthe sides of the car so that this car may be moved during the switching operations without having projections protruding from its sides which are liable to interfere with passing objects.

' From what has been described it will be apparent as to what the invention herein comprises, the description herein setting forth one specific form which the invention may take.

Fig. 5 sets forth more in detail how the movable portions of the elements 3 and 5 may be swung inwardly as stated.

Referring more particularly to Figs. 3

and l, I show a truck which may be of the ordinary automobile type having the wheels 17. 17 and having the hopper 18, which hop-v per hasa bottom portion formed of a circular section 19, a straight section 20, and a further circular section 21.. The straight section permits the hopper 18 to remain in its normal position. A chain 22 'is attached at the points 23 and 2f to the sides of the hopper 1S and extends around suitable rollers to a driving wheel 23, which driving wheel through the agency of the shaft 2& may be suitably rotated to tilt the hopper 18 either to the right or to the left for discharging purposes as the case may be.

By referring to Fig. 4: it will be seen that the hopper 18 may also be tilted backwardly without interfering with the operation of .he parts heretofore described as this tilting takes place along an axis lying in the plane of the chain 22.

Having thus set forth certain forms which my invention may take, what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described having two elements comprising a framework, each element consisting of a rail and downwardly projecting portions adapted to straddle a wall, the protruding ends of each element being mounted to swing inwardly toward said wall, and a hopper adapted to ride .upon said elements and to hold said elements in position.

' A device of the character described having a framework including a rail and means for setting said framework to straddle a wall, a movable hopper movable upon said ail, the protruding end of said rail being mounted to swing toward said wall. and means for defining the throw of said hopper.

A device of the character described having a framework including a runway and means for setting said framework to straddle a wall, a movable hopper movable upon said runway, and means whereby the protruding end of said runway may be swung inwardly.

4. A device of the character described having a framework including a rail and means for setting said framework to straddle a wall, a movable hopper tiltable in opposite 'upon said raiL-and means whereby the directions from its upright position movable trading end of said rail may be collapsed.

5. A v loading and unloading apparatus comprising a skelton framework, a movable hopper thereon,means whereby said hopper can roll unobstructedly on said framework from either side to the other. of.its central position, said opposite limiting positions representing respectively charge receiving and discharge positions, means to limit-the movement of said hopper in one of its limiting positions so that it is 'tilted sufliciently to receive a charge, and means to automatically limit the movement of the hopper to its limiting alternative position whereby it is tilted sutliciently to discharge its load.

6. A loading and unloading apparatus comprising a framework, a movable hopper thereon. means whereby said hopper can roll unobstructedly on said framework from either side to the other of its central position. said opposite limiting positions representing re iectively charge receiving. and discharge positions. means to limit the mo mentof said hopper in one of its lin... positions so that it is tilted sufficiently receive a charge, and means to automatically limit themovement of the hopper to its limiting alternative position whereby it is tilted sufiiciently to discharge its load.

'7. A loading and unloading apparatus comprising a framework, a movable hopper thereon, means whereby said hopper can roll unobstructedly v on said framework from either side to the other of its central position. said opposite limiting positions representing respectively charge receiving and discharge positions, means to limit the move ment of said hopper in one of its limiting positions so that itis tilted suiiiciently to receive a charge, and means to automatically limit the movement of :the hopper to its limiting alternative position whereby it is tilted suiiiciently to discharge its load. said two last aforesaid means being interconnected between said hopper and said framework.

In witness whereof. I hereunto subscribe mv name this 16th day of October A. 1).,

ALBERT I. Llill.
